Final answer:
To compare the values of 0.3 and 0.25, we add a zero to 0.3, making it 0.30, and then compare the hundredths place. Since 30 is greater than 25, 0.3 is the larger number.
Step-by-step explanation:
To determine which number has the greater value between 0.3 and 0.25, we simply compare the two values directly. We can see that 0.3 is the same as 0.30 when we add a zero to the end to have the same number of decimal places for comparison. Now, comparing 0.30 and 0.25, it is clear that 0.30 is larger because 30 is greater than 25 when we look at the hundredths place. This comparison does not require knowledge about significant figures or the multiplication of values, as it is based solely on the place value of the decimals.
